Reduce sshd logging

sshd was configured to log a lot of information on every connection. I
found this polluted the log and wasn't useful. This changes the log
level to FATAL.

This also turns off the TCPKeepAlive option since our netstack doesn't
support it and logs on every connection:
  netstack: convSockOpt: TODO SOL_SOCKET optname=9
